Urinary Ssystem

the "working" parts of the urinary system are:

main function of the urinary system

Although not its main function, the kidneys manufacture substances that reesult in changes in other parts of the body. As an example, the kidneys release renal erthropoietin which influences what?

bean-shaped organs which lie against the muscles of the posterior abdominal wall, just above the waistline

nephr

pyelo

root word meaning "pertaining to the kidney"

basin or collection area within the pelvis

tube that transports urine from the kidney to the bladder; term literally means "to make water"

place where the ureter leaves the renal pelvis

space that holds urine; "chalice or cup"

outside part of the kidney

structura and functioning unit of the kidney (These structures are so small it is impossible to see them without a microscope)

basin in the kidney that collects urine from the calyx and drains it into the ureter

functioning unit of the kidney; tiny, very sophisticated manufacturing plants

Inside each nephron is a collecting tubule that carries urine to the kidney; collection of capillaries in the nepron that resembles a small ball of yarn

small tubes that make-up the system by which urine flows through the nephron

section of the tubes closest to the glomerulus

loop that connects the proximal tubule with the distal tubule

tube that collects and carries urine from the tubules to the calyx of the kidney

process in which the glomerulus acts as a filter to begin the process of removing the by-products of body metabolism from the blood

process in the system of tubules by which certain products are eliminated and certain products were reabsorbed (This is the area where the water content and concentration of by-products occurs)

these attach to the base of the renal pelvis of each kidney. They take urine to the bladder

this has the triangular shape of a funnel which allows urine to drain into the connecting drain or ureter.

point where the ureters attach to the bladder

after the urine leaves the bladder, it flows into another tube called the

urine starts its formation in the kidneys as it progresses through the nephrons. What is the main function of the nephrons?

an organ resembling a bag, its function is to store urine. When it becomes full enough to stretch, we have the sensation to "void"

Important info. regarding the bladder

sac or organ that is the recepticle for fluid-urine

root word meaning "bladder"

triangular internal surface of the posterior wall of the bladder

small opening or mouth of the urethra as it leaves the bladder

pertaining to the bladder

the tube or pipe that carries the urine to the outside of the body

2 functions the urethra serves in males

system involving the reproductive and urinary organs

opening of the urethra to the outside of the body

The action of the urinary bladder is under the influence of voluntary or involuntary nervous systems?

absence of urine

inflammation of the urinary bladder

involuntary pasing of urine

condition in which there is permanent disease of the kidney

inflammation of the glomeruli of the kidneys

condition in which there is blood in the urine

condition in which the person is unable to "hod" his urine

presence of stones in the kidney

frequent urination during the night

involuntary urination that occurs at night (bed-wetting)

production of a scant or small amount of urine

inflammation of the kidney pelvis

condition in which a person has frequent and excessive episodes of thirst ( this is ususally accompanied by polyuria-urinating many times) sometimes called frequency

urinating many times

kidney stones which is also known as nephrolithiasis

stops filtering or forming urine

waste products normally found in the urine , are not filtered through the kidney and remain in the blood

removal of the bladder

measurement of the efficiency and capacity of the urinary bladder

passing of a viewing device into the bladder for visualization of the inside of the bladder

drug used to cause an increased flow of urine

procedure in which blood from an individual is shunted through a special device in which waste products are seperated out and removed from the blood (The cleande blood continues through the device and is sent back to the individual)

method of seperating out waste products by special procedures utilizing the peritoneal cavity and membrane (There is a constant flow of solution into and out of the peritoneal cavity

x-ray of the kidney pelvis following injection into a vein of a radiopaque substance (This test may be eliminated in the not too distant future becasue of advances in digital imaging technology)

act of taking a kidney from a donor and surgically implanting it into a recipient

removal of a kidney

cutting into the kidney to remove stones

substance potentially damaging to the kidney
